The split seal ring press-fitting tool according to the present embodiment includes a sleeve 600 and a push rod 700.
Referring to fig. 2, the sleeve 600 has two sleeve segments 610 having a semicircular ring shape, the two sleeve segments 610 being formed in such a manner as to divide the sleeve 600 into two parts on the circumference. The two sleeve segments 610 are joined together by the sleeve clips 600 c. The sleeve 600 is molded by using MC nylon or the like.
Each sleeve segment 610 is provided with a bolt insertion hole 630 and an engagement projection 640. One bolt insertion hole 630 is provided at a position of about 90 degrees in the sleeve segment 610, and the engaging projection 640 is provided at a position of about 30 degrees and about 150 degrees in the sleeve segment 610. A coupling recess 670 is provided on an end surface of one sleeve segment 610, and a coupling protrusion 680 is provided on an end surface of the other sleeve segment 610. The coupling recess 670 is coupled to the coupling projection 680, thereby maintaining the annular sleeve 600.
Referring to fig. 3 and 4, when viewed from the side of the sleeve segment 610 where the engaging projection 640 is provided, an inner circumferential surface of the sleeve segment 610 on the side closer to the lever 100 is provided with: a first plane 610a parallel to the surface of the bar 100; a first inclined surface 610t1 inclined radially outward from the first flat surface 610 a; a second flat surface 610b extending from the first inclined surface 610t1 in parallel with the surface of the lever 100; a second inclined surface 610t2 inclined toward the outside from the second flat surface 610 b; and an arc surface 600p that is recessed outward in the radial direction in an arc shape from the second inclined surface 610t 2.
The end of one sleeve segment 610 is provided with a locking claw 650, and the end of the other sleeve segment 610 is provided with a locking hole 660. When the sleeve segment 610 is attached to the lever 100, the sleeve 600 can be easily fixed to the outer peripheral surface of the lever 100 by engaging the engagement claws 650 with the engagement holes 660.
In the present embodiment, the description has been given of the case where the sleeve 600 is configured by two sleeve segments 610, but the number of the sleeve segments is not particularly limited as long as two or more sleeve segments are provided.
Push rod 700
Referring to fig. 5 and 6, the push rod 700 has four push rod segments 710 having a circular arc shape, the four push rod segments 710 being formed in such a manner as to divide the push rod 700 into four parts on the circumference. The four pushrod segments 710 are joined together by the pushrod elastic piece 700 c. The push rod 700 is molded using MC nylon or the like.
Referring to fig. 7, the inner circumferential surface of the pushrod patch 710 contacting the rod 100 is a flat surface 710 p. On the other hand, the outer circumferential surface of the pushrod segment 710 includes: a first outer peripheral surface 711; a second outer circumferential surface 712 having a radial length smaller than that of the first outer circumferential surface 711; and a third outer peripheral surface 713 having a radial length smaller than that of the second outer peripheral surface 712. A protruding portion 714 protruding outward in the radial direction is provided below the third outer peripheral surface 713, and a fourth outer peripheral surface 715 recessed inward in the radial direction is provided below the protruding portion 714.
The distance H1 from the surface of the rod 100 of the protrusion 714 is substantially the same as the distance H2 (see fig. 9), and the distance H2 is the distance from the surface of the rod 100 to the bottom surface 600p of the arc surface 600p when the sleeve 600 is assembled to the first stem head 201 when a split seal ring is assembled, which will be described later.
As shown in fig. 5 and 6, in the putter 700, the putter segments 710 are coupled together by the putter dome 700 c. As a result, as shown in fig. 8, when the push rod 700 is assembled to the rod 100 in a state where the push rod elastic piece 700c is folded, for example, the diameter of the rod 100
In contrast, in the case where the push rod 700 is attached to the rod 100 in a state where the push rod elastic piece 700c is stretched, for example, the diameter of the rod 100
Becomes 160. In this way, a single push rod 700 can be used for rods of various diameters.
In the present embodiment, the case where the push rod 700 is configured by four push rod segments 710 has been described, but the number of push rod segments divided is not particularly limited as long as two or more push rod segments are provided.
Pressing the split packing 400 into the club head 200
A step of pressing the split seal ring 400 into the head 200 using the split seal ring pressing tool according to the present embodiment will be described with reference to fig. 9 and 10.
Referring to fig. 9, when the split seal ring 400 is replaced, the head 200 is separated into the first head 201, the second head 202, and the third head 203. Next, the sleeve 600 is fitted to the first head 201. When the sleeve 600 is fitted to the first head 201, the engaging projection 640 provided on the sleeve 600 is inserted into the bolt through hole 201h of the first head 201.
The sleeve 600 defines a guide region G1 communicating with the recess 201a between the inner peripheral surface of the sleeve 600 and the rod 100 in a state of being fitted to the first head 201.
The split seal ring 400 is fitted to a portion of the outer circumferential surface of the rod 100 in the vicinity of the sleeve 600. In this case, no particular problem occurs in the positioning of the split seal ring 400.
The putter 700 is fixed to a portion of the outer circumferential surface of the shaft 100, which is exposed between the first head 201 and the second head 202.
Referring to fig. 10, the putter 700 is moved toward the first head 201 side (the direction of arrow F in fig. 10). At this time, the split seal 400 is pushed by the plunger 700 and also moves, and thereby the split seal 400 is fitted into the recess 201a provided in the first stem head 201.
The distance D from the upper end surface of the recess 201a to the arc surface 600p provided in the sleeve 600 is defined to be equal to the sum of the width D1 of the split seal ring 400 and the distance D2 from the upper end surface of the plunger 700 to the protrusion 714.
As a result, when the putter 700 is moved toward the first head 201, it is confirmed that the protrusion 714 is fitted on the arc surface 600p (the protrusion 714 is engaged with the arc surface 600p), and thus it is possible to confirm that the split seal ring 400 is pressed into an appropriate position in the recess 201a provided in the first head 201. The arc surface 600p and the protrusion 714 constitute a positioning engagement region.
The distance to the arc surface 600p means a distance to a point of the arc surface 600p where the recess is deepest, and the distance to the protruding portion 714 means a distance to a point of the protruding portion 714 where the protrusion protrudes most.
When the split seal ring 400 is press-fitted into the recessed portion 201a, as shown in fig. 4, the second inclined surface 610t2, the second flat surface 610b, the first inclined surface 610t1, and the first flat surface 610a are provided on the inner circumferential surface of the sleeve 600 so that the inner diameter thereof gradually decreases. Accordingly, in the guide region G1, the distance between the inner peripheral surface of the sleeve 600 and the outer peripheral surface of the rod 100 gradually decreases as the inner peripheral surface of the sleeve 600 moves toward the recessed portion 201a, and therefore, the split seal ring 400 can be easily press-fitted into the recessed portion 201 a.
Then, the sleeve 600 and the putter 700 are detached, and the first head 201 and the second head 202 are fastened using the fastening bolt B1, thereby forming the configuration shown in fig. 1.
As described above, the split seal ring press-fitting tool according to the present embodiment can easily press-fit the split seal ring 400 to a predetermined position by using the sleeve 600 and the push rod 700.
It should be understood that all the contents of the embodiments disclosed herein are exemplary, and are not intended to limit the present invention. The scope of the present invention is indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
